JOURNAL-BEARING.

Specification of Letters Patent.

Patented Aug. 2st, 1909.

Application filed June 26, 1907. Serial No. 380,950.

To all whom 'it may concern:

Be it known that I, HENRY Hess, a citizen of the United States, residingat Wawa, in the county of Delaware and State of Pennsylvania, haveinvented certain new and useful Improvements in J ournal-Bearings, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to journal bearings, and more particularly to thatclass thereof deslgned to sustain both radial and end thrust from theconnected parts. In the present case it is shown as applied to bearingsof a type known in the art and illustrated for instance in theLetters-Patent to C. S. Lockwood, No. 813,905, February 27, 1906. In theLetters-Patent mentioned, the rollers are of the well known conical typeand are provided at their ends with additional conically-formed crownsor apices,

which latter are designed to sustain the end thrust on the bearing. Therollers are arranged in double series and so that the crowns or apicesof one series abut against and roll in contact with the crowns or apicesof the other series. In practice, due to slight lrregularities in theshape or size of the rollers or of the race-way wherein they travel,such irregularities arising either from defects in original constructionor from subsequent wear, it often happens that the exact alinement ofthe rollers is lost, and consequently that the friction and resistancein the bearing is largely increased thereby, and that the durability andlife of the parts are further impaired.

It is the purpose of my invention to correct this imperfect alinement,and I therefore employ an independently rotatable part or member havinga continuous bearing-surface, against which. the conical crowns orapiees abut. This member may be formed and arranged in many differentways, some of which are herein illustrated and described.

Referring to the drawings: Figure 1 is a longitudinal sectional view ofa bearing embodyin my invention, taken substantially on the fine ll-ofFig. 2. Fig. 2 is a transverse sectional view, taken substantially onthe line 2-2 of Fig. 1. Fi s. 3, 4, and 5 are sectional views, similarto t at given in Fig. 1, but showing different forms and adaptations ofmy invention.

In Figs. 1 and 2, the bearing is shown as composed of two outer piecesI) and D and an inner piece B connected to the shaft A. The pieces D andD are provided with inclined surfaces d and al and the piece B withinclined surfaces 1) and 6 between which surfaces 05, al and b, 6 theconical rollers C, C, and C C are received and held in angular relationto the shaft, all in the customary manner, and so as to provideantifrictional support to the radial pressure upon the bearing. Therollers C, C, and C C also have sonically-formed crowns or ends, 0, c,and c 0 respectively, which are designed to take the end-thrust, andWlllCll abut against and have a rolling contact with the plate, ring, orwasher E, formed withan unbroken or continuous surface, so as to reduceto a minimum the friction thereon. The ring E is held in positionbetween the two series of rollers C, C, and C C each series thusopposing the end thrust'on the other. In the form shown the ring E 1smounted on anti-friction balls, 6, e, d1sposed about the iece B, and istherefore capable of a rotational movementwithin the bearing, thus stillfurther reducing the resistance and friction of the parts.

In Fig. 3, the arrangement is substantially similar to that justdescribed, except that to provide for a difference in the amount of endthrust from opposite sides, the rollers C C do not occupy the sameangular relation with respect to the rollers, C, O. TlHS necessitates achange in the cross:sect1onal form of the ring or plate E as Wlll beapparent from the drawing. It may also be noted that the ring E iscapable of rotational movement in the bearing, although not providedwith the anti-friction balls, previously mentioned.

In Fig. 4, where end thrust 1n one direction only is to be taken up,only one series of rollers C C is illustrated, and' hence a differentmeans is necessary for mountingthe ring or plate E which is shown as incontact with. anti-friction balls f, f, disposed between the ring E andthe end plate F of the bearing. In this way, not only is resistanceafforded to end thrust, but the ring is capable of rotational movement,as before.

In Fi 5, the devices are substantially a duplication of those in Fig.4:, there be ng two sets of rollers, as in Fig. 1, two res stlng rings Eand E and two sets of anti-friction balls, g, g, and g, g the rings andanti-friction balls being disposed on opposite sides of aninternally-arranged flange F of the bearing.

These and many other modifications I regard as comprised within thescope of my invention, which in its broad form is-the combination ofangularly arranged rollers having conical crowns or apices and anindependently rotatable bearing-member against which they abut and roll.

Having thus described my invention, what I claim and desire to secure byLetters-Patent of the United States is as follows:

1. In a journal bearing, the combination with casing members and aseries of angularly arranged rollers, each having at its end aconically-formed abuttin portion, of a suitably supported indepen entlyrotatable member havlng a continuous bearing-surface which contacts withthe said abutting portions, the said member thus afiording re- 4sistance to the end thrust on the rollers.

2. In a journal bearing, the combination with caslng members and aseries of conical rollers, each having also a conically-formed abuttingportion, of a suitably supported independently rotatable member having acontinuous bearing-surface which contacts with the said abuttingortions, the said member thus affording reslstance to the end thrust onthe rollers.

3. In a journal bearing, the combination with casing members and aseries of angularly arranged rollers, each havingat its end aconically-forined abutting portion, of an independently rotatable memberhaving a continuous bearing-surface which contacts with the saidabutting portions, the said member being suitably supported and mountedto' turn in the journal bearing and to afford resistance to the endthrust on the rollers.

In testimony whereof I have affixed my signature in presence of twowitnesses.
